Dermatite infecciosa associada ao HTLV-I (DIH) infanto-juvenil e do adulto Infective dermatitis associated with the HTLV-I (IDH) in children and adults

A dermatite infecciosa associada ao HTLV-I (DIH) é um tipo de eczema infectado e recidivante que incide em crianças que adquirem verticalmente a infecção pelo HTLV-I. Inicia-se após os 18 meses de idade. No entanto, existe relato recente de início na vida adulta. As lesões são eritemato-descamativas, infectadas e freqüentemente crostosas. Localizam-se, com maior freqüência, no couro cabeludo, regiões retroauriculares, pescoço e região inguinal, mas podem ser generalizadas. Vêem-se também físsuras retroauriculares, pápulas eritêmato-descamativas e foliculares. Prurido discreto a moderado, secreção nasal crônica e blefaroconjutivite podem ser observados. A DIH sempre se associa à infecção por Staphylococcus aureus e/ou Streptococcus beta hemoliticus. O diagnóstico diferencial clínico deve ser feito com as dermatites atópica e seborréica e, do ponto de vista anatomopatológico, com a psoríase e o linfoma cutâneo de células T. São discutidos os aspectos clínico-imunopatológicos, o diagnóstico diferencial e a evolução da DIH. Considerando a freqüência da DIH em Salvador, aconselha-se que seja feita sorologia para o HTLV-I em todos os casos de eczema severo em crianças e que essa possibilidade diagnóstica também seja considerada em adultos.<br>Infectious dermatitis associated with HTLV-I (IDH) is a form of infected and recurrent dermatitis which affects children vertically infected with HTLV-I. IDH starts after 18 months of age. The lesions are erythematous-scaly and frequently crusty and are more frequently located on the scalp and on the retroauricular regions, but the lesions may be generalized. Pustules, erythematous-scaly and follicular papulae and retroauricular fissures may also be observed. Children present mild to moderate pruritus, lesions in the nostrils, and blepharoconjunctivitis. IDH is always associated with Staphylococcus aureus infection and/or Streptococcus beta haemolyticus infection. The differential diagnosis with atopic and seborrheic dermatitis can be made clinically. Histologically it is important to make a differential diagnosis with psoriasis and cutaneous T-cell lymphoma. We discuss here the clinical-immuno-pathological aspects, the differential diagnosis, and the evolution of IDH. Considering the frequency of IDH in Salvador, Bahia, we suggest that children with severe eczema be submitted to routine serology for HTLV-I and that IDH be included in the differential diagnosis of dermatitis in adulthood

Body mass index and complications following major gastrointestinal surgery: A prospective, international cohort study and meta-analysis

Aim Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major postoperative complications in an international cohort and to present a metaanalysis of all available prospective data. Methods This prospective, multicentre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma or formation of stoma. The primary end-point was 30-day major complications (Clavien\u2013Dindo Grades III\u2013V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis was used to analyse pooled results. Results This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese vs normal weight patients (13.0% vs 16.2%, respectively), but this did not reach statistical significance (P = 0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. Individual patient meta-analysis demonstrated that obese patients undergoing surgery formalignancy were at increased risk of major complications (OR 2.10, 95% CI 1.49\u20132.96, P &lt; 0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46\u20130.75, P &lt; 0.001) compared to normal weight patients. Conclusions In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease
